LOCOMOTIVE FRONT PLATE.

SPECIFICATION forming part of Letters Patent No. 423,517, dated March18, 1890.

Application filed March 12, 1889. Serial No. 303,017. (No model.)

To all whom it may concern:

Be it known that I, EDWARD WILLIAM MAC- KENZIE-HUGHES, of Chicago, Cookcounty, Illinois, have invented a new and useful Improvement inLocomotive Front Plates, of which the following is a full, true, andexact description, reference being had to the accompanying drawings.

This invention relates to an improved construction of locomotive frontplate and number-plate combined, by which the door of the front plate islocked bythe same bar which supports the front plate.

My invention will be readily understood from the accompanying drawings,in which Figure 1 represents an elevation of my front plate in position,and Fig. 2 a horizon tal section through the same; Fig. 3, a view,partly in vertical section, showing the arraugement of the lockingdevice.

The parts A, K, and H of this structure are all, by preference, made ofpressed steel, pressed between dies to the forms indicated.

A represents the front plate itself. To this is hinged by hinge O thesmoke-box door K. The number-plate is shown at H, supported upon the rodD, which has at its inner end the T-head for locking the door. Withinthe front plate A, which is preferably corrugated at B, is the cross-barF, provided with an opening, through which the head E of the bolt D willpass in one position, but when turned nut G and turning the number-plateat right angles the bolt D will draw through the bar F and the door Kcan be opened. By reversing the operation the door can be tightly closedagainst the front plate.

What Iclaim as myinvention, and desire to secure by Letters Patent, is

1. The combination of locomotive front plate and door herein shown,which consists of a front plate and door hinged thereto, a transversebar within the front plate, a bolt carried by the door and having a headlooking in one position within the cross-bar and in another positionpassing therethrough, and a nut outside the, door for locking the samewhen closed, substantially as described.

2. The combination of a boiler front plate, a door hinged thereto, and across-bar within the same, a bolt carried in Said door and passingthrough said cross-bar for locking the door, the said bolt likewisecarrying a number-plate at its outside end, and a nut for locking thedoor in its closed position, substantially as described.

3. The combination of the front plate A, the door K, hinged thereto, thebar F, having lon gitudinal opening theret-hrough, and a bolt D, passingthrough the bar F and on its outer end carrying the number-plate H andnut G, substantially as described.

In testimony whereof. I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD WILLIAM MACKENZIE-HUGHES.
